Displacement scale. The displacement scale indicates:
1.Displacement at varying draughts and the number of tonnes required to increase the draught of the ship one centimetre at the various draughts. This number is not a fixed number but varies according to the draught. In light conditions fewer tonnes are required to put down the ship one centimetre on account of the fine lines of the ship’s structure.
2.Deadweight capacity in tonnes at different draughts.
3.Maximum draughts on winter, summer and tropical loadlines.
